Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Actinopterygii (ray-finned fishes) > Beloniformes (Needle fishes) > Adrianichthyidae (Ricefishes) > Oryziinae
Etymology: Oryzias: Greek, oryza = rice; because of the habitat used by this fish (Ref. 45335);  orthognathus: Greek, orthos = right + Greek, gnathos = jaws (Ref. 45335).   More on author: Kottelat.

Environment / Climate / Range Ecology

Freshwater; benthopelagic; pH range: 7.5 - 8.5; non-migratory.   Tropical; 22°C - 25°C (Ref. 31267); 1°S - 3°S, 120°W - 121°W (Ref. 26747)

Asia: Endemic to Lake Poso, Sulawesi, Indonesia.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 6.5 cm TL male/unsexed; (Ref. 31267); common length : 5.0 cm TL male/unsexed; (Ref. 27139)

Short description Morphology | Morphometrics

Dorsal soft rays (total): 8-11; Anal soft rays: 23 - 25. Distinguished from all other species of the genus by its upturned mouth. Differs further by having 45-54 scales in lateral row, 8-11 dorsal rays and 23-25 anal rays (Ref. 26747).

Biology     Glossary (e.g. epibenthic)

Non-annual breeder. Is very difficult to maintain in aquarium (Ref. 27139).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00192 - 0.01252), b=3.13 (2.91 - 3.35), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming fec < 100).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
